Subject: [PATCH] fix(tui): proper box corners on column ticket area
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the full-width ▔▔▔ underline bar with ┌──┐ as the top border of
the ticket box. The ▔ row had no │ side characters so the box corners were
open/disconnected when the ticket area sides started on the next row.
Now the box is closed: ┌──┐ top, │ │ sides, ╘══╛/└──┘ bottom.
The pill name row above it still provides the visual tab header.
